COMBINED SASH LOCK AND OPENER.

Specication of Letters Patent.

Patented Mar. 21, 1911.

.Application filed April 23, 1908. Serial No. 428,754.

To all whom it may concern:

Be it known that I, CLINTON D. TABoR, a citizen of the United States,residing at New Dorp, in the county of Richmond and State of New York,have invented a new and useful Improvement in Combined Sash Locks andOpeners, of which the following is a specification.

This invention relates to opening and locking means which are applicablemore particularly to centrally pivoted sashes which are capable of botha horizontally swinging movement and also a vertically sliding movementin the frame.

The object of this invention is to provide simple and eflicient meanswhereby these functions can he easily and reliably performed.

In the accompanying drawings consisting of 2 sheets: Figure 1 representsan inside elevation of a sash and frame provided with my improvements.Fig. 2 is a vertical section thereof in line 2 2, Fig. 1. Fig. 3 is ahorizontal section in line 3--3, Fig. 1. Fig. 4 is a fragmentaryvertical section on an enlarged scale taken in line 4-4, Fig. l, andshowingthe position of the sash ,opening and locking device when thesash is closed. Figs. 5, 6 and are views similar to Fig. 4 showingdiiferent positions of the sash opening and locking device. 9 and 10 areperspective views showing the parts of the sash opening and locking de-`vice detached. Fig. 11 is a fragmentary vert-ical section in line 11-11,Fig. 1.

Similar letters of reference indicate corresponding parts throughout theseveral side jambs and a horizontal head jamb 5 connecting the upperends of the side jambs.

6 represents the sash which is capable of turning in a horizontal planeand also of sliding vertically in vthe frame. For this purpose the sashis pivoted centrally by its upper and lower rails 7, 8 by any suitablemeans. In the closed position of the sash the same is in line with theframe and engages by means of an` outwardly facing shoulder 9 on itsoutwardly closing stile 12 with an inwardly facing shoulder or stopFigs. 8, y

its inwardly closing stile 12a with an outwardly facing shoulder or stop13 on the adjacent side jamb 3 of the frame while its lower rail 8 restsupon a stool 14 secured to the upper side of the main sill. rlhe spacebetween the top rail and the head jamb is closed by a follower or strip15 which engages with its under side against the upper edge of the toprail while its upper edge is arranged in a pocket or a recess 16 formedbetween inner and outer cleats, strips or bars 17, 17 secured to theunderside of the head j amb. While in this closed posit-ion a weathertight joint is produced between the bot-tom rail and stool by means of alongitudinal rib 18 formed on the upper side of the stool and engagingwith a longitudinal groove 19 on the underside of the bottom rail andthe joint between the top rail and the follower is also rendered weathertight by means of a longitudinal rib 21 formed on the underside of thefollower and engaging with a longitudinal groove in the upper side ofthe top rail, as shown in Fig. 11.

The pivotal connection between the lower rail of the sash and the stoolcomprises a sill plate 22 secured centrally to the upper side of thestool and provided with an upwardly proj eeting pivot pin 28 whichenters a socket formed partly in a lower sash plate 24 which is securedcentrally to the underside of the lower rail and partly in said railabove the plate 22.

The pivotal connection between the upper or top rail of the sash, thefollower' and the head jamb consist-s of a vertical pin 25 secured atit-s upper end to the head j amb and arranged with its lower part in acentral opening` 26 in the follower and a socket 27 in the top rail andalso through coinciding openings 28, 29 formed in pivot plates 30, 31which are secured respectively to the upper side of the top rail and theunderside of the follower, as shown in Fig. 2.

The follower is yieldingly held in its depressed posit-ion in engagementwith the top rail of the sash by a spring 36 surrounding the upper pivotpin 25 and bearing at its upper end against the base of said pin whileits lower end bears against the upperside of the follower plate 31.

Upon turning the sash from its closed and lowered position the wedgeaction of the ribs and grooves between the lower end of the sash and theframe causes the sash to be lifted until the lower rail of the sashreaches the top of the lower ribs after which it rests on top of theseribs and remains in this vertical position upon swinging the sashhorizontally into a more or less open position. While thusl raising andturning thev sash the follower rises with it and is raised an additionalextent by the wedge action of the cooperating upper ribs and groovesbetween these parts. Upon swinging the sash back into its closedposition into line with the frame the sash drops with its lower grooveover the rib on the stool and the follower descends with its rib intoengagement with the groove of the head rail.

My improved means for opening the sash and locking the same in itsclosed position are constructed as follows :H37 represents an uprightlocking plate secured to the face of the jamb 2 by screws or otherwiseand provided with a forwardly projecting locking lug 38. The latter isprovided at its front end with an upwardly projecting lip 39 forming anoutwardly facing shoulder -LLO while its inner end is curved or roundeddownwardly and outwardly to a downwardly facing shoulder Ll1 on theunderside of this lug.

42 represents a pivot plate secured to the edge of the sash stile l2 andprovided with an inwardly projecting pivot lug 43 which carries a pivotpin or stud 44 projecting laterally toward the adjacent side jamb 2 ofthe frame. Upon this stud is pivoted the upper end of a verticallyswinging handle or hand lever l5 which has its lower end constructed inthe form of a hook-shaped finger piece for convenience in taking hold ofthe same with a finger. Below its pivot this handle is provided with anupwardly facing shoulder #il which is adapted to engage with thedownwardly facing shoulder 41 of the locking lug 3S on the frame.Projecting inwardly and downwardly from the handle adjacent to its pivotis a locking dog 4G which is adapted to engage with the inwardly facingshoulder at its front end with the outwardly facing shoulder on theupper side of the locking lug 40. Above its pivot the handle is providedwith a heel or tail piece 4S which is arranged at an angle to the handleand adapted to engage with the adjacent part of the locking lug plate orother stationary part on the frame.

lVhile the sash is swung into its closed and lowered position land theopening' and locking device is in its operative position the handle isarranged vertically and engages with its upwardly facing shoulderagainst the downwardly facing shoulder on the underside of the lockinglug, the locking dog engages its end with the rearwardly facing shoulderof the locking lug and the heel is separated from the frame. as shown inFig. fl. In this position of the parts it is impossible to raise thesash owing to the engagement of the handle shoulder with the undersideof the locking lug and it is also impossible to turn the sashhorizontally owing to the engagement of the dog with the outwardlyfacing' shoulder of the locking lug. It is therefore impossible to openthe sash from the outside of the building and it is also impossible toopen the sash from the inside of the room except by manipulating theopening and locking device. 1When it is desired to open the sash, thehand lever first swung inwardly and upwardly until its locking dogclears the outwardly facing shoulder of the locking lug and the heelthereof bears against the adjacent part of the sash or locking plate, asshown in Fig. 5, and upon then continuing this upward and inwardmovement of the handl-e and sash is simultaneously raised and itsswinging side is moved inwardly. during which movement the upwardlyfacing shoulder, of the handle swings inwardly and upwardly around thecurved face of the locking lug and clears the same so that the sash canbe swung wide open. As the tail of the hand lever engages the frameduring this inw-ard and upward movement of the handle a lifting effectis produced on the sash which relieves the wedge action of thecooperating inclined surfaces of the rib and groove on the stool and thebottom rail, thereby causing these parts to wear less and the sash to beopened more readily and easily.

lVhen the sash has been fully opened and the handle is released theparts of the opening and locking device assume the relative position,shown in Fig. 6. Upon subsequently turning the sash in the direction forclosing the same the'parts of the locking device remain in this positionuntil the sash has nearly completed its closing movement at which timethe locking dog engages with its underside against the top of thelocking lip, as shown in Fig. 7. As the sash completes its horizontalclosing movement and drops into its lowered position the locking dog islifted by the lip together with the handle and when the dog has clearedthis lip it drops into engagement with the shoulder on the outer side ofthis lip and` the handle swings with its lower shoulder around thecurved end of the looking lug and into engagement with the shoulder onthe underside thereof, as shown in Fig. 4, whereby the sash is againlocked against upward and inward movement. This operation of locking thesash is wholly automatic and effected solely by swinging the sash into.its closed position in line with the frame, thereby dispensing withseparate closing and locking operations for this purpose. By thuscombining the sash opening and locking device in one structure thefittings which ordinarily would be required for this purpose on a windowof this character are materially reduced and the appearance of the sameis much improved.

I claim as my invention:
